God Is Still at Work in Us / Colossians 2:6-15

A common reductionism within modern Christian thought is the tendency to view the gospel exclusively as an entry point—a historical moment of conversion rather than the continuous, sustaining power of the Christian life. When salvation is conceptualized merely as a past transaction, believers inadvertently mirror the Galatian error, attempting to attain spiritual maturity through human striving after having begun by the Spirit. In his Epistle to the Colossians, the Apostle Paul directly counters this deficiency. He presents the gospel not as a static threshold crossed in the past, but as an active, dynamic reality wherein God continually conforms the believer to the image of His Son.

Paul establishes this theological foundation by tying the proclamation of Christ to the continuous sanctification of believers, laboring with divine energy to present every person mature in Christ.

Colossians 1:28-29 (NASB)

We proclaim Him, admonishing every man and teaching every man with all wisdom, so that we may present every man complete in Christ. For this purpose also I labor, striving according to His power, which mightily works within me.

The Christian life is defined by this divine trajectory: the same grace that initiates faith is the grace that sustains and completes it.

Rooted, Built Up, and Established: The Dynamics of Sanctification

Paul moves from his cosmic exposition of Christ’s supremacy to the practical outworking of that truth in daily conduct. Authentic Christian orthodoxy must inevitably culminate in orthopraxy; genuine apprehension of the exalted Christ overflows into transformed behavior.

Colossians 2:6 (NASB)

Therefore as you have received Christ Jesus the Lord, [so] walk in Him,

The exhortation to “walk in Him” rests upon how Christ was initially received. The phrase “Christ Jesus the Lord” carries profound theological precision: He is the promised Messianic King (Christ), the historical incarnate Savior (Jesus), and the sovereign ruler over all creation (Lord). To receive Him is to submit to the apostolic doctrine regarding His person and work. The imperative to walk is in the present tense, signaling continuous, habitual motion. Christian conduct is not a sequence of disconnected moral efforts, but a persistent walk in union with Christ.

The grammatical architecture of the subsequent verses reveals the divine initiative undergirding this walk.

Colossians 2:7 (NASB)

having been firmly rooted [and now] being built up in Him and established in your faith, just as you were instructed, [and] overflowing with gratitude.

Paul weaves together agricultural and architectural metaphors, utilizing precise Greek verbal aspects to articulate how spiritual growth occurs. The phrase “having been firmly rooted” appears in the perfect passive tense. This denotes a past, completed action accomplished entirely by God, the effects of which continue into the present. The believer does not root themselves; God firmly anchors them into the rich soil of Christ’s life and power, mirroring Christ’s teaching on the true vine.

John 15:5 (NASB)

’I am the vine, you are the branches; he who abides in Me and I in him, he bears much fruit, for apart from Me you can do nothing.

Conversely, the terms “being built up” and “established” are present passives. They describe an ongoing, continuous construction and strengthening occurring within the believer by the hand of God. Just as a master builder lays an unshakable foundation upon which the superstructure rises, God continually erects and confirms the believer’s faith.

1 Corinthians 3:10 (NASB)

According to the grace of God which was given to me, like a wise master builder I laid a foundation, and another is building on it. But each man must be careful how he builds on it.

Within this divine work, the single active responsibility assigned to the believer in this passage is “overflowing with gratitude.” While God accomplishes the rooting, the building, and the establishing, the posture of the redeemed heart is one of unceasing thanksgiving. Gratitude is the metric of spiritual health, acknowledging that every dimension of sanctification is a gift of sovereign grace.

Philippians 1:6 (NASB)

[For I am] confident of this very thing, that He who began a good work in you will perfect it until the day of Christ Jesus.

The Plumb Line of Christ Against Empty Deceptions

The necessity of being firmly anchored in Christ becomes evident when evaluated against the perennial threat of spiritual seduction. Paul cautions the church against intellectual and cultural currents that seek to displace the supremacy of Christ.

Colossians 2:8 (NASB)

See to it that no one takes you captive through philosophy and empty deception, according to the tradition of men, according to the elementary principles of the world, rather than according to Christ.

The Apostle identifies three interrelated perils: human philosophy disconnected from divine revelation, empty deception rooted in human tradition, and the “elementary principles of the world.” Paul does not issue an anti-intellectual mandate; rather, he warns against any worldview, societal convention, or philosophical system that functions to the disregard of Christ. When human reason or tradition sets itself up as the ultimate arbiter of truth, it takes the mind captive.

Paul’s apologetic method does not require exhaustive mastery of every worldly counterfeit. Instead, he presents Christ as the supreme standard and plumb line against which all ideologies must be measured. Just as an authentic currency note immediately exposes a forgery, a robust theology of Christ readily unmasks hollow philosophies. The goal of doctrinal maturity is stability against cultural drift.

Ephesians 4:14-15 (NASB)

As a result, we are no longer to be children, tossed here and there by waves and carried about by every wind of doctrine, by the trickery of men, by craftiness in deceitful scheming; but speaking the truth in love, we are to grow up in all [aspects] into Him who is the head, [even] Christ,

The cultural currents of the first century—much like those of the present age—insinuated that full human flourishing required supplementing or abandoning divine truth in pursuit of autonomy. Paul dismantles this lie by highlighting the absolute sufficiency of Christ.

Colossians 2:9-10 (NASB)

For in Him all the fullness of Deity dwells in bodily form, and in Him you have been made complete, and He is the head over all rule and authority;

In Christ, the totality of the divine essence (pleroma) permanently dwells in bodily form. Consequently, those who are united to Him by faith have been filled and brought to completeness. Believers do not need to look outside of Christ for spiritual vitality, meaning, or identity. Because Christ is the sovereign head over every cosmic power and authority, seeking fulfillment apart from Him is pursuing empty shadows when the substance has already been granted.

Regeneration: From Spiritual Death to Spiritual Life

The sufficiency of the believer in Christ is rooted in the dramatic reality of regeneration. Paul illustrates this spiritual transformation through covenantal imagery.

Colossians 2:11-12 (NASB)

and in Him you were also circumcised with a circumcision made without hands, in the removal of the body of the flesh by the circumcision of Christ; having been buried with Him in baptism, in which you were also raised up with Him through faith in the working of God, who raised Him from the dead.

Under the Old Covenant, circumcision served as an external sign of covenant belonging. In Christ, believers experience a spiritual circumcision “made without hands”—the internal removal of the governing power of the fallen nature. This inner transformation is publicly signified and sealed in baptism, which dramatizes the believer’s spiritual burial and resurrection with Christ through faith in God’s resurrecting power.

This transformation is essential because of humanity’s original condition apart from grace.

Colossians 2:13 (NASB)

When you were dead in your transgressions and the uncircumcision of your flesh, He made you alive together with Him, having forgiven us all our transgressions,

Scripture does not describe the unregenerate state as spiritual weakness or illness, but as absolute spiritual death. Dead in trespasses and sins, humanity possessed neither the inclination nor the power to initiate reconciliation with God. Yet, by sovereign initiative, God made believers alive together with Christ, granting the total forgiveness of all transgressions.

The Victory of the Cross: Canceled Debt and Public Triumph

The ground of this total forgiveness lies in the finished, substitutionary work of Christ at Calvary, where the legal barrier separating holy God from sinful man was permanently eradicated.

Colossians 2:14 (NASB)

having canceled out the certificate of debt consisting of decrees against us, which was hostile to us; and He has taken it out of the way, having nailed it to the cross.

Paul utilizes the imagery of a handwritten certificate of debt (cheirographon)—a formal, legally binding record listing every moral infraction and divine decree violated by the sinner. Under the weight of God’s holy law, this document stood as an insurmountable accusation, hostile to human survival. On the cross, God did not merely set this debt aside; He canceled it, blotted out its legal validity, and nailed it to the wood of the cross. The debt was fully paid, satisfying the justice of God and rendering the accuser entirely powerless.

Having dismantled the legal basis of condemnation, Christ achieved a decisive, cosmic victory over the spiritual forces of darkness.

Colossians 2:15 (NASB)

When He had disarmed the rulers and authorities, He made a public display of them, having triumphed over them through Him.

Drawing upon the imagery of a Roman triumphal procession (triumphus), Paul depicts Christ as a victorious conqueror. In ancient warfare, a conquering general would parade disarmed, captive enemy kings and generals through the streets, displaying their complete subjugation to public view. At the cross, an event the world perceived as absolute defeat, Christ stripped the principalities and powers of their authority, exposing their ultimate impotence and triumphing over them.

Conclusion

The message of Colossians 2:6–15 establishes that the gospel is not merely the doorway of salvation, but the entire house in which the believer lives. Having received Christ Jesus the Lord, the Christian is called to walk habitually in Him, rooted in His life, built up on His foundation, and established in the faith. Because all the fullness of deity resides in Christ, and because believers have been made complete in Him, there is no need to turn to human tradition or worldly deception for spiritual wholeness.

The Christian’s debt has been nailed to the cross, the powers of darkness have been vanquished, and the dead have been made alive. Sanctification is the continuous outworking of this supreme reality. As God continues His sovereign, transforming work, the appropriate and enduring response of the redeemed is an unceasing overflow of gratitude, walking securely in the triumphant sufficiency of the risen Lord.
